About E66
This is an older-series code, taken from Electrolux dryer tech sheet 137265000B, shown with model EIMED6CJIW. It stands for a thermal limiter open circuit, and the chart’s main reading is that the outlet thermal limiter tripped.
Conditions named
The outlet thermal limiter has tripped.
The inlet thermal limiter has tripped, but only on a gas model.
The wiring is defective.
Technician sequence
With the limiter open, look it over for signs of high-temperature damage.
If there is no such damage, replace the limiter.
If the limiter is sound, check the exhaust for a blockage.
Then check or replace the high-limit thermostat and test the dryer again.
Leave the plug out of the wall throughout.
Looking up the last code
Cancel and Start Pause, held together for 6 seconds, bring up the latest code on record. E00 appears if no failure code occurred.
An older dryer in San Francisco showing E66 can be raised on (415) 449-0036, where Electrolux dryer repair is arranged. Mention the code, the model number and the steps you took.
Model compatibility: Electrolux reuses codes across series and model years, so E66 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
